The back is in tension.
Any wrapping going around the bow will stiffen it a tad but won't add much in the way of increased resistance to tension along the back.
If you think it will blow anyway, why not try the patch?
Just think of the physics... just like the recent thread about butt splicing a bow. The unanimous opinion was an overlay over the joint. It worked.

No more from me on this thread... honest, yes, really....

That is a giant crack. I'd superglue it and I'd do a sinew wrap to the end of the crack.
When I tiller a knot, I leave the knotted area  a little stiffer than the rest of the limb.

Nothing left for me to say about possible fixes, all my heroes have chipped in. 

I just wanted to ask for more photos, preferably with the rest of the bow.  That one pic was a tease!

Try drilling a hole right through the limb (thickness) where the crack stops. It cant get past that hole and that hole wont hurt the bow.
Only when the last tree has died and the last river has been poisoned and the last fish has been caught will we realize we cannot eat money.

Oooof that's a brave idea!  The logic makes sense.  Might need a new pair of undies...

I see no reason it wont work! The hole only needs to be a 2-3mm at most.

Fine :D

These aren't finished photos - the tiller was tweaked and the bow oiled since but this should give a rough idea.  I don't usually take full draw photos for various reasons, but I'm getting nagged to death by people about this one, so I might take one later and add it in here as well. 

It's English Yew, somewhere between 50 and 60lb at 27" (or 28" with a deadly-sounding ticking soundtrack)

Has it been done somewhere I can see it?  Sounds like an amazing fix, but I think seeing a successful bow with it having been used would ease the nerves a bit!

Glass bow guys do it all the time. The truth of the matter is glass will act the same way when a crack starts. Plus, looking over your new pictures I doubt a 2-3 mm hole will even be noticed by that wood!

Interesting.  Cheers for the idea - I'm gonna give it a go, and wrap as the other guys suggested as well!  I only need one extra inch of draw to be happy enough to sell this one so fingers crossed!

Thanks for the photos, Will.  She's quite the character and I am sincerely hoping she works out for you!  Wow, what a looker!
